"Step S101"

Perform the status check and initial setting of the washer-dryer.

"Step S102"

The display 7 of the operation panel 8 is opened, and the laundry stroke is set in accordance with the instruction input of the operation key switch 6. In the state where there is no instruction input, it is automatically set to the standard laundry stroke or the last executed laundry stroke.

"Step S103"

The instruction input from the start switch 6a of the operation key switch 6 of the operation panel 8 is monitored, and the divergence processing is performed.

"Step S104"

Perform a wash dose detection process. The washing dose detecting is a washing dewatering driving motor 13 and an electromagnetically operated clutch mechanism 12 for controlling the washing and dewatering driving device when the rotary blade 11 is rotated in a single direction while the washing tank 9 is in a stationary state in a dry cloth state before the washing water is supplied. The amount of the laundry is detected based on the amount of the rotating load acting on the rotary wing 11, and an appropriate amount of the lotion (washing amount) is obtained based on the detected amount of the cloth.

The washing dose is determined based on a comparison table of the amount of cloth and the washing amount set in advance. Specifically, the detection of the amount of cloth is performed by using the inverter drive motor as the washing and dehydrating drive motor 13, and the washing and dehydrating drive motor 13 is rotated, and the rotation speed at the time of power supply for a predetermined time is detected. In the case where the capacitor phase-separated single-phase induction motor is used as the structure of the washing and dehydrating drive motor 13, the inertial rotation deceleration after the power-off is detected by the power supply until the washing and dehydrating drive motor 13 is raised to the saturation rotation speed. Features to carry out. The preferred wash dose is determined by reference to a pre-set amount of cloth and wash dose.

The amount of the washing water is set such that the amount of the washing water is maintained so as not to exceed the water level of the rotary wing 11 as it is stored at the bottom of the outer tub 10 when the cloth amount is within a predetermined cloth amount range (appropriate amount). Further, the washing time is set based on the detection result (amount of cloth). When the cloth amount detection is not performed, it is set to the standard laundry time.

"Step S105"

The determined washing dose is displayed on the display 25 of the operation panel 8.

"Step S106"

Open the lotion supply solenoid valve, to the lotion. The lotion supply chamber of the softener container 28 is supplied with a lotion. The user puts the indicated amount of powder lotion into the lotion. After the lotion of the softener container 28 is put into the chamber, the outer lid 3 is closed. The powder lotion is put into the lotion input chamber where the lotion is supplied with water, and the lotion is passed through the lotion together with the water supplied by the lotion. The softener inlet 28a falls to the bottom of the outer tank 10.

"Step S107"

The water supply is stopped when the water supply reaches the dissolved water level of the lotion. In the present embodiment, the amount of the lotion supply is independent of the washing amount (the amount of cloth), and is uniformly set to about 10 liters. The amount of water in the subsequent lotion dissolving step (step S108), when the washing tank 9 is rotated, is sufficient to stir the water and the lotion at the bottom of the washing tank 9. And the water surface is set lower than the height below the rotary wing 11 (the laundry does not get wet before the lotion dissolves).

"Step S108"

By gradually rotating the washing tank 9 and the rotary wing 11 in a single direction (about 70 revolutions per minute), the lotion which is put into the bottom of the outer tank 10 dissolves water and powder on the bottom surface of the washing tank 9. The lotion is stirred, and the lotion which produces the washing water having a high lotion concentration is dissolved. It takes only 1 minute for the lotion to dissolve. Even at low temperatures (low water temperature), it is about 90% dissolution rate under the condition of a powder detergent which is not easily dissolved. The resulting wash water has a lotion concentration of about 7 times. Here, the ratio of the standard concentration is: a powder washing dose of 20 g / a washing water amount of 30 liters.

"Step S109"

Perform pre-washing. This pre-washing is performed by intermittently rotating the rotary vane 11 in a state where the washing tank 9 is stationary, and by rotating the circulating pump 16 during the forward and reverse rotation of the rotary vane 11, the pre-washing can be performed from the nozzle. 34 The washing water at the bottom of the outer tank 10 is poured onto the laundry. During the stop period of the rotary wing 11 and the circulation pump 16, the wash water supply solenoid valve and the laundry water supply solenoid valve are opened while referring to the detection signal of the water level sensor 21, and the supplementary water supply is performed in such a manner that the set water level is not exceeded. By repeating this operation several times, the laundry is immersed in the washing water and dispersed on the rotary wing 11.

At the time of the first positive reversal, the washing water having a concentration of about 7 times the lotion is poured onto the laundry to permeate the laundry. Because of the high concentration of laundry The water is sprinkled from the nozzle 34 to the laundry, so that the soaking action by the lotion can completely penetrate the laundry. The high-concentration washing water soaked in the laundry has high dissolving power and can dissolve the grease and dirt, so that the dirt floats out of the laundry, and excellent detergency can be obtained.

By replenishing the water supply in turn, the concentration of the washing water to the laundry can be lowered, and after the pre-washing completion stage, it becomes about twice the standard concentration.

"Step S110"

Perform formal laundry. In the formal laundry, the same method as above is used to detect the amount of cloth, and the set laundry time is corrected. Then, while the washing tub 9 is stationary, the circulating pump 16 is operated while the rotating blade 11 is being reversed, and the stirring is performed for about 2 minutes, and the stirring is performed to store the washing water stored at the bottom of the outer tub 10. The washing water circulation from the nozzle 34 to the laundry, and the agitation of the loose laundry in about 1 minute, the loose washing agitation is to stop the circulation pump 16, and the rotary wing 4 is reversed in a state where the washing water stops circulating. . By the forward and reverse rotation of the rotary wing 11, the laundry can be alternately rotated in the circumferential direction and the radial direction in the washing tank 9, and is sufficiently washed. Finally, the average agitation is performed for about one minute, and the operation of stopping the circulation pump 16 is stopped, and the rotary vane 11 is reversed in the state where the washing water circulation is stopped, and the time for the official laundry is ended.

"Step S111"

Perform the first water storage cleaning. In the water storage washing, first, the drain valve 15 is opened, and the washing water stored in the bottom of the outer tank 10 is discharged, and the washing tank 9 and the rotary vane 11 are integrally rotated in one direction, and the washing water contained in the laundry is centrifugally dehydrated. The rotation speed of the washing tank 9 and the rotary vane 11 when the washing water is dehydrated is set to be the same as the rotation speed (about 1000 rpm) at the time of final dehydration described later, and the dehydration operation is performed to practice a high dehydration rate.

Thereafter, the drain solenoid valve 15 is closed, and the washing tank 9 and the rotary vane 11 are integrally rotated in a single direction (about 35 to 40 rpm), and the washing water supply solenoid valve is opened to supply water, so that tap water is sprinkled from the spout to the rotary vane. Washing on 11.

Next, in a state where the washing tank 9 and the rotary wing 11 are stopped from rotating, the water supply to the washing water is performed so that the water level at the bottom of the outer tank 10 does not exceed the set water level.

Next, the washing water circulation agitation cleaning is performed, and the washing water circulation agitation washing is the same as the pressure washing agitation in the case of the official washing, and the circulating pump 16 is operated while the rotary vane 11 is reversed while the washing tank 9 is stationary. The washing water stored at the bottom of the outer tank 10 circulates from the head 34 to the laundry on the rotary wing 11.

After that, when the rotary blade 11 stops rotating and the circulation pump 16 stops operating, the water level is detected so as not to exceed the set water level while detecting the water level of the washing water stored in the bottom of the outer tank 10.

Next, the washing water is circulated and stirred, and the washing water is washed. In the state in which the washing tank 9 is stationary, the circulating pump 16 is operated while the rotating blade 11 is being reversed, and the washing water stored in the bottom of the outer tank 10 is sprayed from the nozzle 34 onto the rotating wing 11 General cycle. As in the case of laundry, the laundry in the washing tank 9 is alternately rotated in the circumferential direction and in the radial direction, so that the washing water can be completely dripped into the laundry to dilute the lotion.

Finally, the circulation pump 16 is stopped, and in the state where the washing water circulation is stopped, the average stirring for continuously rotating the rotary vane 11 is performed.

"Step S112"

The second water storage washing was performed. The second water storage cleaning is to open the softener water supply solenoid valve, by washing the lotion. The softener is supplied to the softener supply chamber of the container 28 to supply water, and the softener introduced into the chamber is introduced into the bottom of the outer tank 10. The other actions are the same as the first water storage laundry.

"Step S113"

The final dehydration treatment is carried out. The final dehydration is such that the washing and washing tank 9 and the rotary vane 11 are integrally rotated at a high speed of about 1000 rpm in a single direction while the drain solenoid valve 15 is kept open, and the washing and dewatering driving device is operated to wash in the washing tank 9. The material was subjected to centrifugal dehydration. The operation time of this final dehydration is set to the time at which the desired dehydration rate can be obtained.

"Step S114"

Check if the laundry drying schedule has been set and disagree.

"Step S115"

Dry the clothes when setting the laundry dryer stroke. The dry clothes are in a state in which the drain solenoid valve 15 is kept open, and in the same state as the washing step, the blower provided in the drying duct 22 is operated while the rotary vane 11 is reversed while the washing tank 9 is stationary. 19, the air in the outer tank 10 is sucked from the water vent 10b toward the drying duct 22, and when passing through the inside of the drying duct 22, it comes into contact with the cooling from the dehumidifying mechanism 22b provided in the drying duct 22. The water is cooled and dehumidified, and then the cotton dust is collected by the cotton filter, and after being heated by the heater 20, it is blown from the hot air outlet toward the washing tank 9. The dry clothes are performed while monitoring the temperature of the hot air by the temperature sensor 26, and are stopped when the ratio of the temperature change becomes a predetermined value.

With respect to the upright washing and drying machine having such a configuration, the characteristic configuration of the present invention and the operation will be described next. Here, first, a specific configuration and a schematic function of the present invention will be described, and then a specific control operation will be described.

In the embodiments shown below, an embodiment in which hot air is blown from the side surface portion of the washing tub 9 and an embodiment in which hot air is blown from the surface of the rotating blade 11 will be described. One of the reasons for distinguishing between the hot air blowing positions is that the movement of the clothes differs depending on the configuration of the rotary blades 11.

For example, when the shape of the rotary wing 11 is such that the clothing is easily moved toward the outer peripheral side due to the rotation of the rotary wing 11, it is preferable to use an embodiment in which hot air is blown from the side surface portion of the washing tub 9.

Further, when the shape of the rotary blade 11 is such that the clothing is less likely to move toward the outer peripheral side due to the rotation of the rotary blade 11, or the rotary blade 11 is not easily rotated, it is preferable to use an embodiment in which hot air is blown from the surface of the rotary blade 11. .

From this point of view, Fig. 6 shows an embodiment in which hot air is blown from the side surface portion of the washing tub 9, and Fig. 12 shows an embodiment in which hot air is blown from the surface of the rotary wing 11. The following is a detailed description of each embodiment.

In the present embodiment, as described above, the configuration in which the stirring air is blown from the side surface portion of the washing tub 9 is displayed.

In Fig. 6, reference numeral 50 denotes a drying unit of a drying mechanism 50 which houses a blower fan 19, a heater 20, and the like shown in Fig. 2 . The extension tube 29b is connected to the outlet of the drying unit 50, and the extension tube 29b is also connected to a hot air outlet opening that faces the washing tank 9.

Further, as shown in FIGS. 7 and 8, the bellows fixing portion 51 to which the bellows 29b is fixed and the wind direction plate 52 directed to the inner center of the washing tank 9 are integrally formed in the outer tank casing 31b. A hot air branch hole 53A is formed in the bellows fixing portion 51, and the hot air branch hole 53A is derived from a drying sheet. The hot air AW1 of Yuan 50 is divided. As will be described later, the hot air branch holes 53A are generally branched so as to blow hot air from the side surface portion of the washing tub 9.

In this manner, the hot air AW1 from the bellows 29b is taken as the hot air AW2, and the wind direction plate 52 opening toward the washing tank 9 is blown toward the inner center of the washing tank 9, and the hot air AW3 is also blown from the side surface portion of the washing tank 9. The hot air branch hole 53A is connected to a passage forming pipe 53C that forms a passage for sending out the hot air AW3. The passage connecting pipe 53C is also integrally formed in the outer tank casing 31b, and the hot air AW3 is flowable by the passage forming body 54 spanning the hot air branching hole 53A and the passage connecting pipe 53C.

Further, as shown in FIG. 6, the hot air AW3 which is supplied from the extension tube 29b is supplied to the side surface blowing forming portion 57 provided on the inner peripheral side surface of the washing tank 9. The side blow forming portions 57 are provided in a plurality of equidistant manners on the inner circumference of the washing tank 9, and in the present embodiment, four are equidistantly arranged every 90 degrees. The hot air blown to the side surface forming portion 57 is from the passage connecting pipe 53C shown in Fig. 8 . The passage connecting pipe 53C is connected to the side surface hot air passage 58 shown in Fig. 6 .

The side air blowing forming portion 57 is provided with a plurality of hot air blowing holes 59 provided in the longitudinal direction, and the hot air blowing holes 59 are passed through to blow hot air from the side surface of the washing tank 9. In the present embodiment, the direction in which the hot air blowing holes 59 are directed is blown at right angles to the inner peripheral wall surface of the washing tub 9. However, it is also possible to blow out obliquely in the upward direction, so that the clothes can be further blown up.

Further, the total area of the through holes 9a formed in the inner circumferential surface of the washing tank 9 facing the hot air blowing hole 59 is set to be larger than The total area of the through holes 9a adjacent thereto. That is, the total area of the through holes 9a penetrating through the region corresponding to the hot air blowing holes 59 (including the enlarged shape) is larger than the total area of the through holes 9a of the other same areas. As a result, the hot air blown from the hot air blowing hole 59 is more easily passed, and the stirring action can be further enhanced.

The configuration of the rotary wing 11 is as shown in FIG. The rotor blade 11 has a configuration in which the clothes are easily moved toward the outer peripheral side by rotation. In Fig. 9, the upper surface of the rotor blade 11 is composed of a plurality of raised portions 11A and a valley portion 11B formed between the raised portions 11A, and is formed by sandwiching the rotation center P of the rotary wing 11 The two raised portions 11A and the two valley portions 11B formed between the raised portions 11A. The raised portion 11A and the valley portion 11B are curved from a radial position on the outer peripheral side toward a single arc in a single direction. When viewed from above, the raised portion 11A and the valley portion 11B are slightly S-shaped, and the left and right sides are asymmetrical, but The center of rotation P is point symmetrical.

The height of the raised portion 11A is gradually increased from the center of rotation toward the outer peripheral direction. Further, the valley portion 11B has a bowl-shaped concave curved surface and has an inclined surface 11L facing the outer side. In order to increase the movement of the laundry in the vertical direction, the height of the outer peripheral portion 11M of the bowl-shaped concave curved surface is lower than the height of the highest portion of the raised portion 11A. The outer peripheral end surface 11F of the swelled portion 11A is an inclined surface that tilts the upper portion toward the center side.

In order to fix the rotary vane 11 to the washing and dewatering driving device, a bulging portion 11N that protrudes upward is provided around the rotation center P to secure a space for accommodating the fixing screw. At the bottom of the bowl-shaped concave surface of the valley 11B The face has a plurality of ridges 11D that are curved in the same direction as the ridges 11A. The curved shape is substantially the same as the raised portion 11A. The ridge 11D is sandwiched between the valleys 11B, and is disposed at each position at the same angle, and is disposed at a point symmetrical position (four in total) for the rotation center P.

Further, a plurality of spherical crown-shaped bulging portions 11E are provided on the upper surface of the rotary wing 11. The bulging portion 11E is a portion that is disposed to be disposed outside the region above the ridge portion 11A. The ridge 11D and the bulging portion 11E have the effect of a washboard, which can improve the detergency. Even on the upper surface of the rotary wing 11, there are a plurality of holes 11C for water passage. The hole 11C is a portion that is disposed to be disposed in the top region of the raised portion 11A, the protrusion 11D, and the bulging portion 11E.

Further, the plurality of holes 11C may be used as a hot air blowing hole 11C for blowing hot air from the surface of the rotor blade 11 as will be described later. Therefore, in the following description, a description will be given of a plurality of holes 11C as the hot air blowing holes 11C.

Next, the operation in the above configuration will be described. 6, 10, and 11 show a case where the hot air AW3 is blown out from the side surface of the washing tub 9 by the side blowing forming portion 57. In Fig. 6, the hot air AW1 from the drying unit 50 is blown from the wind direction plate 52 provided in the outer tank casing 31b toward the upper inner side of the washing tank 9, and is blown toward the high-speed hot air AW2 obliquely downward, and mainly has: wet clothes C Dry drying function and "stretching pleats" that stretch the "wrinkles" of clothing C. The "stretch wrinkle" function is in the state where the clothes C is accumulated in the bottom of the washing tank 9 However, it is not possible to fully play, and the clothes C must be blown up, and the clothes can be fully functioned while the clothes are free to move.

The function of blowing the clothing C can be achieved by the side blowing forming portion 57 described below. As shown in FIG. 6, the hot air AW1 from the drying unit 50 flows into the hot air branch hole 53A in the middle, passes through the passage forming pipe 53C, and flows as the hot air AW3 to the side surface side hot air passage 58 which is provided on the outer peripheral side of the outer tank 10. The hot air AW3 that has flowed out toward the side surface hot air passage 58 flows into the outer tank 10 through the connection pipe joint 60, reaches the side surface blowing forming portion 57 provided on the inner circumferential surface of the washing tank 9, and is blown out from the hot air blowing hole 59 at a high speed. The hot air blowing hole 59 is formed through the side blowing forming portion 57.

Here, between the outer tub 10 and the washing tub 9 which are higher than the side blow forming portion 57, the fluid resistance of the annular space is increased, and the hot air AW3 is more efficiently flowed into the side blow forming portion 57. In order to increase the fluid resistance, various methods are used. For example, the annular space gap is small, that is, a labyrinth structure is formed in the annular space.

In this manner, the high-speed hot air AW3 blown from the hot air blowing hole 59 formed in the side surface blowing forming portion 57 can blow the clothes C remaining in the bottom of the washing tank 9 to agitate. The hot air blown from the hot air blowing hole 59 has a function of drying the clothes C because of the high temperature. Further, the air for stirring does not necessarily have to be hot air, and it is only required to have a function of blowing the clothes C. However, if hot air is used, the drying time can be further shortened.

Here, when the hot air AW3 is blown out from the side, It is preferable that the class C is sent to the vicinity of the inner peripheral wall surface of the washing tank 9, and therefore, the rotary wing which can be sent to the outer side as shown in Fig. 9 is used to rotate the rotary wing 11, and the clothes C are sent to the washing tank by centrifugal force. In the vicinity of the inner peripheral wall surface of the nine, in this state, the hot air AW3 is blown out from the side surface blowing forming portion 57, whereby the clothing C can be effectively blown up. Therefore, it is preferable that the side blowing forming portion 57 is disposed at a position close to the bottom surface of the washing tank 9, and it is preferable to provide the height in the vicinity of the outermost circumference of the rotating blade 11.

Furthermore, since the clothes C is wet, it becomes heavy, so it must be blown up to a certain extent. Therefore, it is necessary to first dry the clothes C to a predetermined dryness (drying rate) by drying air blown from the wind direction plate 52. This control action will be described later using a control flow chart.

10 and FIG. 11 show the state of the drying step, and the hot air AW3 flowing through the side side hot air passage 58 flows between the outer tank 10 and the washing tank 9 through the joint pipe joint 60, and is further blown from the side forming portion 57. The hot air blowing hole 59 is blown out. At this time, since the rotary blade 11 rotates at a low speed, the clothing C is sent to the outside by the centrifugal force of the rotary blade 11. Therefore, the clothing C is blown up by the high-speed hot air blown by the hot air blowing hole 59 of the side surface side blowing forming portion 57, and is blown up in the washing tank 9, and the side surface side blowing portion 57 is provided in the inner circumference of the washing tank 9. side.

The blown up garment C is lowered by the air pressure of the drying hot air AW2 from the wind direction plate 52, and is again blown up by the high-speed hot air AW3 blown from the hot air blowing hole 59 of the side surface side blowing forming portion 57. Repeat this situation. In this state, because from the wind direction board The high-speed drying of 52 is blown to the clothes C by the hot air, so that the moisture remaining in the clothes C can be evaporated and dried. Even in this step, since the high-speed hot air AW2 acts on the clothes C, the surface or the back of the clothes C is The hot air AW2 is pressed or stretched, and the "wrinkle" can be stretched.

Here, the speed of the drying hot air AW2 blown from the wind direction plate 52 is set to be larger than the hot air AW3 blown by the hot air blowing hole 59 that blows the forming portion 57 from the side surface side. As a result, when the drying hot air AW2 blown from the wind direction plate 52 is increased, the "wrinkles" can be more effectively stretched. According to experiments by the inventors, the speed of the drying hot air AW2 blown from the wind direction plate 52 is preferably 50 m/s or more, and if the speed is 60 m/s or more, the effect of stretching the clothes "wrinkles" is obtained. It will be even bigger. Therefore, the hot air AW2 having a speed of 60 m/s or more can be completely blown to the clothes blown by the hot air blown from the hot air blowing holes 59 of the side surface blowing forming portion 57, and the "wrinkles" on the clothes can be stretched. To eliminate "wrinkles". In addition, the speed of the hot air AW2 blown from the wind direction plate 52 is also set to the same speed in the embodiment in which the hot air AW3 is blown from the surface of the rotor blade 11 to be described later.

In this manner, the drying air, preferably hot air, is blown to the clothes existing in the bottom of the washing tank to dry the clothes, and the drying is performed by using the stirring air blown from the side of the washing tank. By drying the air for drying to the blown clothes, drying the clothes and stretching the wrinkles, so that the clothes can be dried and the clothes can be dried. Clothing effect.

Next, the description will be made from the surface of the rotary wing 11 of the washing tank 9. The configuration of the stirring air is taken out and the operation is performed. The configuration shown in Fig. 12 is based on the hot air blowing hole 59 provided with the side surface side blowing forming portion 57 shown in Fig. 6 . Therefore, the configuration shown in FIG. 6 and FIG. 12 is provided at the same time, but the following description is directed to a configuration in which hot air is blown from the surface of the rotor blade 11.

In Fig. 12, the hot air AW3 from the passage connecting pipe 53C passes through the bottom side hot air passage 55 and is supplied to the bottom space 56 between the bottom surface of the outer tank 10 and the bottom surface of the washing tank 9, which is branched from the bellows 29b. The bottom space 56 is connected to the bottom of the rotary wing 11 by a through hole 9b (refer to FIG. 2) provided at the bottom of the washing tank 9. The rotor blade 11 is formed with a hot air blowing hole 11C that connects the front surface and the back surface.

12, 13 and 14 show the case where the hot air AW3 is blown from the rotary wing 11 to the upper side of the washing tank 9. In Fig. 12, the hot air AW1 from the drying unit 50 is blown out from the wind direction plate 52 provided on the outer tank casing 31b toward the upper side of the washing tank 9, and is blown out as a high-speed hot air AW2, and mainly has a dry type of dried clothes C. The function of the clothes and the "wrinkle stretch" function of the "wrinkle" of the stretched clothes. This "stretch wrinkle" function cannot be fully exerted in the state where the clothes C is present in the bottom of the washing tank 9, and can be fully exerted in a state where the clothes C can be blown up and the clothes can move freely.

The function of blowing the clothes C is achieved by hot air blown from the following rotor blades 11. As shown in FIG. 12, the hot air AW1 from the drying unit 50 flows into the hot air branch hole 53A in the middle thereof, passes through the passage forming tube 53C, and flows as the hot air AW3 to stand outside the outer tank 10. The bottom side hot air passage 55 on the side of the circumference.

The hot air AW3 flowing out toward the bottom side hot air passage 55 flows into the bottom space 56 formed by the bottom surface of the washing tank 9 and the bottom surface of the outer tank 10. The hot air AW3 flowing into the bottom space 56 passes through the through hole 9b of the washing tank 9, reaches the bottom surface of the rotary vane 11, and is then blown out at a high speed from the hot air blowing hole 11C formed in the rotary vane 11 toward the upper side of the washing tub 9.

Here, the fluid resistance of the annular space between the bottom surface portion of the washing tank 9 and the outer tank 10 is increased to effectively flow the hot air AW3 into the side of the rotating blade 11. There are many methods for increasing the fluid resistance, and in the present embodiment, the configuration is such that the void in the annular space is made small.

In this manner, the high-speed hot air AW3 blown from the hot air blowing hole 11C formed in the rotary blade 11 can blow the clothes C having the bottom of the washing tank 9 and stir them. The hot air blown from the hot air blowing hole 11C can also dry the clothing C because of the high temperature. Further, by blowing the hot air AW3 from the hot air blowing hole 11C of the rotor blade 11, the clothing C can be blown more efficiently.

Here, when the hot air AW3 is blown out from the hot air blowing hole 11C of the rotary wing 11, it is not necessary to rotate the rotary wing 11 frequently as compared with when it is blown from the side surface of the washing tank 9. Therefore, it is expected to reduce the effect of power consumption. Even the rotary wing 11 can be used for a washing machine having a rotary wing that does not require the delivery of the garment to the outer peripheral side.

Further, since the clothes C become heavy once they are wet, they must be blown up in a certain degree of dry state. Therefore, it is necessary to use the drying air blown from the wind direction plate 52, first to the clothes C Drying is performed until the predetermined dryness (drying rate). This control action will be described later using a control flow chart.

13 and FIG. 14 show the state of the drying step, in which the hot air AW3 flowing in the bottom side hot air passage 55 flows into the bottom space 56 between the outer tank 10 and the washing tank 9, and further from the hot air blowing hole 11C formed in the rotary wing 11. Blow it out. Therefore, the clothes C are blown up by the high-speed hot air blown by the hot air blowing hole 11C of the rotary wing 11 to the upper side, and are blown up in the washing tank 9. The blown-up garment C is lowered by the wind pressure of the drying hot air AW2 blown by the gravity or the wind direction plate 52, but is again blown up by the high-speed hot air AW3 blown by the hot air blowing hole 11C of the rotary wing 11. Repeatedly.

In this state, since the high-speed drying hot air AW2 blown from the wind direction plate 52 is blown to the clothes C, the moisture remaining in the clothes C can be evaporated and dried, even in the process, because the high-speed hot air AW2 acts on the clothes. C, the surface or the back surface of the clothing C is pressed or stretched by the hot air AW2, and the "wrinkles" can be stretched. Here, the speed of the drying hot air AW2 blown by the wind direction plate 52 is set to be larger than the speed of the hot air AW3 blown from the hot air blowing hole 11C formed in the rotor blade 11. As a result, when the drying hot air AW2 blown from the wind direction plate 52 becomes large, the "wrinkles" can be effectively stretched.

In this manner, the drying air, preferably hot air, is blown to the clothes existing in the bottom of the washing tank, and the clothes are dried, and the drying clothes are blown up by the stirring air blown from the side of the washing tank. Drying by blowing dry air to the blown clothes Drying can stretch the "wrinkles" while drying the clothes, so it can improve the dry state of the clothes and obtain a good drying effect.

Although the above embodiment has been described as an example in which hot air is blown from the side of the washing tub 9 and an example in which hot air is blown from the surface of the rotary vane 11, it is of course possible to control the simultaneous blowing of hot air from both sides. At this time, as long as the hot air baffle hole that divides the hot air AW1 from the heater unit 50 into two is formed in the expansion and contraction fixing portion 51 shown in FIG. 8, the branch holes are connected to the bottom surface side hot air passage 55 and the side surface side hot air passage 58, respectively. Just fine. With this configuration, the hot air AW3 can be blown out from the side surface portion of the washing tub 9 and the rotary wing 11.

Further, in each of the above-described embodiments, the hot air is supplied from the drying unit 50, but the air for the drying and the "stretching wrinkles" (hot air AW2) can be used by the hot air of the drying unit 50, and flows to the bottom side. The air (hot air AW3) of the hot air passage 55 and the side side hot air passage 58 can be used only as unheated stirring air. At this time, two blower fans can be used, one for the drying unit 50 and the other for the air blowing unit that carries the stirring air.

Further, the drying unit 50 can not only send the air heated by the heater, but also introduce the air having a higher temperature as the hot air AW1 because the electric device such as the motor provided outside the outer tank 10 generates heat. Or mechanical heating (because of friction, etc.), the temperature becomes higher.

Next, a detailed control flow of the drying step in the embodiment in which the stirring air is blown from the side surface portion of the washing tank 9 shown in Fig. 6 will be described. Cheng. This control flow is as shown in the flowcharts shown in Figs. 15A and 15B. Further, since step S101 to step S114 of Fig. 15A are the same as the control flow shown in Figs. 4 and 5, the description will be omitted.

In step S114 of Fig. 15A, if the laundry dryer stroke is not selected, the control flow is considered to be final after the completion of the laundry. On the other hand, if the laundry dryer stroke is selected, the following steps are performed.

"Step S200"

This step means that once the drying step is entered, the washing tank 9 is rotated at a high speed in order to further perform the dehydration of the clothes. This step can be omitted if sufficient dehydration has been carried out in the previous washing step.

"Step S201"

This step is for performing the processing of step S200 for a predetermined period of time, and performing the dehydration step until a predetermined predetermined time elapses. This step can also be omitted if sufficient dehydration has been carried out in the previous washing step.

"Step S202"

This step is to dry the clothes present at the bottom of the washing tank 9 after the completion of the dewatering until the predetermined dryness is reached. That is, when the clothes C is wet, the weight becomes heavy, so it is necessary to blow the clothes by the air for stirring in a certain degree of dry state. Therefore, the drying of the clothes C is performed by the drying air blown from the wind direction plate 52 until the predetermined drying degree (drying rate) is predetermined.

Therefore, in this step, while rotating the rotary wing 11 (labeled as a stirrer in the drawing), the drying unit 50 is set to be turned on, and the heater is turned on to supply the hot air AW1. At this time, the hot air is mainly the hot air AW2 blown from the wind direction plate 52. In this case, since the clothes are brought close to the inner peripheral surface side of the washing tank 9 due to the rotation of the rotary wing 11, the side surface is blown to form. Since the hot air blowing hole 59 of the portion 57 is blocked by the clothes, the ratio of the hot air to the hot air AW2 blown from the wind direction plate 52 is increased. Further, if the hot air AW3 can be blown from the hot air blowing hole 59, the existing state can be maintained. The reason is that since the clothes are light after drying, the clothes can be naturally blown up.

Further, in order to block the hot air AW3 flowing in the side side hot air passage 58, a solenoid valve may be provided in the passage connecting pipe 53C to block. At this time, after completing the following step S203, the solenoid valve can be opened to be controlled.

"Step S203"

This step is for performing the processing of step S202 for a predetermined period of time, and blowing the hot air AW2, the hot air AW2, and the hot air AW3 into the washing tank 9 until a predetermined predetermined time elapses. Once the predetermined time has elapsed, the process proceeds to step S204. If the specified time is exceeded, the garment C is dried to a predetermined dryness to a degree that can be blown up by the hot air AW3. In this state, the clothes C are not completely dried, but are so-called "semi-dry" or a dry state in a slightly wet state.

"Step S204"

In this step, an environment in which a large amount of hot air AW3 flows in is formed in the washing tank 9, and the plurality of hot air AW3 is blown out from the hot air blowing holes 59 provided in the side blowing forming portion 57. That is, the positional relationship between the washing tub 9 and the rotary wing 11 is not fixed but relatively changed. Therefore, the positional relationship between the clothes C and the hot air blowing holes 59 also changes. Therefore, once the hot air blowing hole 59 is blocked by the clothing C, the hot air hot air AW3 may not be efficiently blown into the washing tank 9. In order to eliminate such a problem, the relative positional relationship with the clothes C can be changed while rotating the washing tank 9 (indicated as a stirrer in the drawing). Of course, at this time, the fan of the drying unit 50 is turned on, and the heater is also in an open state, which is a state in which the hot air AW1 is supplied. In this state, the next step S205 is performed.

"Step S205"

In this step, it is determined that a plurality of hot air AW3 flows into the washing tank 9, and the plurality of hot air AW3 are blown out from the hot air blowing holes 59 formed in the side blowing forming portion 57. Therefore, as long as the pressure between the outer tank 10 and the washing tank 9 is monitored, it can be determined which position the washing tank 9 comes into, and more hot air AW3 will be blown into the washing tank 9. Therefore, in this step S205, it is judged whether or not the output of the water level sensor (which senses the use of the pressure sensor) is lower than the predetermined pressure.

As shown in FIG. 2, the water level sensor 21 detects the pressure between the outer tank 10 and the washing tank 9 by a hose, so that when the pressure is high, the hot air AW3 from the hot air blowing hole 59 is blown into the washing tank. Within 9 The ratio becomes small, and when the pressure is lower than the predetermined pressure, the ratio of the hot air AW3 from the hot air blowing hole 59 to the inside of the washing tank 9 becomes high. In this step S205, when the output of the water level sensor is higher than the predetermined pressure, the weight is returned to step S204, and the washing tank 9 is again rotated to perform the determination of step S205. On the other hand, in step S205, when the output of the water level sensor is lower than the predetermined pressure, the process proceeds to the next step S206. That is, when the pressure is lower than the predetermined pressure, the hot air AW3 from the hot air blowing hole 59 is blown into the washing tank 9 in a large proportion, so that the clothes can be effectively blown up.

"Step S206"

This step is performed as a result of the agitation, drying action, and "stretching wrinkle" effect caused by the blowing of the clothing C. That is, in step S205, when it is determined that the hot air AW3 can be effectively blown out from the hot air blowing hole 59, the washing tank 9 is fixed at this position, the environment is maintained, and the number of rotations of the fan of the drying unit 50 is further increased to increase the air volume. . When the number of rotations of the fan does not reach the predetermined number of rotations determined in advance, the process returns to step S205, and the above-described processing is executed again. On the other hand, when the number of rotations of the fan exceeds the predetermined number of rotations, the number of rotations is maintained, and the amount of wind AW1 is increased.

In this way, when the air volume AW1 is increased, the amount of wind of the hot air AW2 blown from the wind direction plate 52 and the hot air AW3 blown from the hot air blowing hole 59 is increased. Therefore, the hot air AW3 blown by the hot air blowing hole 59 can be used. The agitation action caused by the blowing of the clothes C is enhanced, and the strong clothes hot air AW2 blown from the wind direction plate 52 hits the agitated clothes C, thereby promoting the drying of the clothes C, and similarly, the surface of the clothing C or back It is pressed and stretched by the hot air AW2, and it seems to stretch "wrinkle", and it can promote drying and "stretching wrinkles". In the state of this step S206, the number of fan rotations of the drying unit 50 is rotated at a high speed, and the process proceeds to the next step S207.

"Step S207"

In this step, the clothing C is stirred by the process of step S206, and when the clothes C are lowered to the rotary wing 11 in the working state of drying and "stretching wrinkles", the clothes C are sent to the laundry tank 9. The side of the circumference. That is, when the clothes C is lowered and deposited on the surface of the stirring blade 11, the stirring blade 11 itself cannot blow the clothing C, so that the rotating blade 11 is rotated, and the clothes C are sent to the outside by centrifugal force. The clothes C that have been transported are again blown up by the high-speed hot air AW3, and are swung up in the washing tank 9, which is a hot air blowing hole 59 that blows the forming portion 57 from the side surface side provided on the inner peripheral side of the washing tank 9. Blowed out. The blown up garment C is lowered by the wind pressure of the drying hot air AW2 blown from the wind direction plate 52, but is again blown out from the side surface side by the high-speed hot air blown by the hot air blowing hole 59 of the forming portion 57. AW3 is blown up, so repeated. Here, intermittent control is performed, which means that the rotary wing 11 is controlled to rotate only for a predetermined time, and then the rotation is stopped only for a predetermined time. This is to reduce the power consumption of the motor required to rotate the rotary wing 11, and to rotate the rotary wing 11 until the garment C is accumulated to a predetermined amount. Of course, in this state, the fan of the drying unit 50 is turned on, and the heater is also turned on. The clothing C is carried out by the process of this step S207. In the state of drying and "stretching wrinkles", the process proceeds to the next step S208.

"Step S208"

This step is to judge whether the above drying step has been completed. It is judged whether or not the drying step is completed, and it is usually judged by whether or not the drying step has been performed for a predetermined period of time. Further, it is also possible to determine the dryness based on the weight of the clothing C measured at the time of the processing in step S202 and the weight of the clothing C in the drying step, and further determine whether or not the drying step is completed. Even, the temperature sensor 26 can be used to measure the temperature of the hot air AW2, and when the ratio of the temperature change becomes a predetermined value, it is judged that the dry clothes have been completed.

When it is determined in this step S208 that the drying step is not completed, the process returns to step S207, and the rotary blade 11 is again rotated to perform the determination in step S208. On the other hand, if it is determined in the step S208 that the drying step has been completed, it is determined that the drying step is completed, and the process proceeds to the next step S209.

"Step S209"

This step S209 receives the message that the drying step is completed, turns off the fan of the drying unit 50, further turns off the heater, and finally completes the drying step. After that, the control process is completed, that is, a series of processes are completed.

By performing the above-described control flow, the drying air, preferably hot air, is blown to the clothes existing at the bottom of the washing tank to dry the clothes, and the stirring air blown from the side of the washing tank side is used. The dried clothes are blown, and the drying air is blown to the blown clothes to dry the clothes, and the "wrinkles" are also stretched while the clothes are dried, so that the dry state of the clothes can be improved, and good drying can be obtained. Drying effect.

Next, a detailed control flow of the drying step in the embodiment in which the stirring air is blown from the surface of the rotary wing 11 will be described. This control flow is as shown in the flowcharts shown in Figs. 16A and 16B. In addition, since the processing contents are the same as those of FIGS. 15A and 15 having the same component symbols, the description is omitted in order to avoid redundancy.

"Step S300"

This step is a process performed after step S206, and the stop position of the rotary wing 11 is determined. In this step, an environment in which a large amount of hot air AW3 flows in is formed in the washing tank 9, and the hot air AW3 is blown out from the hot air blowing hole 11C formed in the rotary wing 11. That is, the position of the rotary wing 11 is not fixed but relatively changed. Therefore, the positional relationship between the clothing C and the hot air blowing hole 11C formed in the rotary wing 11 also changes. Therefore, once the hot air blowing hole 11C is blocked by the clothing C, the hot air AW3 may not be effectively blown into the washing tank 9. In order to solve this situation, on the one hand, the rotary wing 11 is rotated, on the one hand, the relative positional relationship with the garment C is changed. Of course, at this time, the fan of the drying unit 50 is turned on, and the heater is also turned on to supply the hot air AW1. In this state, the next step S301 is performed.

"Step S301"

This step is a state in which a large amount of hot air AW3 flows into the washing tank 9, and the hot air AW3 is blown out from the hot air blowing hole 11C formed in the rotary blade 11. In order to perform this monitoring operation, as long as the pressure between the outer tub 10 and the washing tub 9 is monitored, when the rotary vane 11 reaches a position, a large amount of hot air AW3 is blown into the washing tub 9 to be judged. Therefore, in this step S301, it is judged whether or not the output of the water level sensor 21 (the sensing system uses the pressure sensor) is lower than a predetermined predetermined pressure. At this time, the water level sensor 21 detects the pressure of the bottom space 56.

Since the water level sensor 21 detects the pressure of the bottom space between the bottom of the outer tank 10 and the bottom of the washing tank 9 through the hose, when the pressure is higher than the predetermined pressure, the hot air AW3 from the hot air blowing hole 11C faces the washing tank 9 The ratio of the inner blowing is small, and when the pressure is lower than the predetermined pressure, the ratio of the hot air AW3 from the hot air blowing hole 11C to the washing tank 9 is large. In step S301, when the output of the water level sensor 21 is higher than the predetermined pressure, the process returns to step S300, and the rotary wing 11 is rotated again to perform the determination of step S301. On the other hand, in this step S301, when the output of the water level sensor is lower than the predetermined pressure, the process proceeds to the next step S302.

"Step S302"

This step is carried out to improve the effect of the stirring action, the drying action, and the "stretching wrinkle" effect caused by the blowing of the clothes C. That is, in step S301, when it is determined that the hot air AW3 can be effectively blown out from the hot air blowing hole 11C, the rotating wing 11 is fixed at the position, and the ring is maintained. Further, the number of rotations of the fan of the drying unit 50 is further increased to increase the air volume. When the number of rotations of the fan has not reached the predetermined predetermined number of rotations, the process returns to step S301, and the above-described processing is performed again. On the other hand, when the number of rotations of the fan exceeds the predetermined number of rotations, the number of rotations is maintained to increase the air volume AW1.

In this way, when the air volume AW1 is increased, the amount of wind of the hot air AW2 blown from the wind direction plate 52 and the hot air AW3 blown from the hot air blowing hole 11C is also increased, so that the hot air AW3 blown from the hot air blowing hole 11C can be reinforced. The agitating action caused by the blowing of the clothing C and the strong hot air AW2 blown from the wind direction plate 52 may hit the clothing C, so that the drying of the clothing C can be promoted. Similarly, the surface or the back surface of the clothing C is pressed by the hot air AW2. Stretching, and stretching "wrinkles" to promote drying and "stretching wrinkles". By the process of this step S302, in a state where the number of fan rotations of the drying unit 50 is rotated at a high speed, the process proceeds to the next step S303.

"Step S303"

This step is for the process of step 302 of the predetermined time, and the hot air AW2, the hot air AW2, and the hot air AW3 are blown into the washing tank 9 until a predetermined time elapses. In this step, when the clothes C are stirred and the "stretching wrinkles" are performed, when the clothes C is lowered to the rotary blades 11, the clothes C are blown upward by the hot air AW3. In other words, when the clothes C is lowered and deposited on the surface of the stirring blade 11, the high-speed hot air blown from the hot air blowing hole 11C of the stirring blade 11 can be blown up again and fluttered in the washing tank 9. The clothes C that are blown up will be heavy because The force or the wind direction of the drying hot air AW2 blown by the wind direction plate 52 is lowered, but it is blown up by the high-speed hot air AW3 from the hot air blowing hole 11C of the rotary blade 11, and is thus repeated. In the state in which the drying of the clothes C and the "stretching wrinkles" are performed in the process of the step S303, the process proceeds to step S304 once the predetermined time has elapsed. Moreover, the predetermined time is determined according to the time required until the clothing C is substantially dry.

"Step SS304"

In the step S303, the rotor 1 is further rotated in a state where the clothes C are dry, and the flow of the hot air AW3 blown from the hot air blowing hole 11C is complicated to improve the stirring of the clothes C. In addition, this step can also be expected to obtain a good drying function.

Thereafter, the processing of steps S208 and S209 is executed in a state where the step S304 is executed, and the control flow is completed.

By performing the control flow described above, drying air, preferably hot air, is blown to the garments present at the bottom of the washing tank to dry the clothes, using the stirring air blown from the surface of the rotary wing of the washing tank. The drying clothes are blown, and the drying air is blown to the blown clothes to dry the clothes, so that the "wrinkles" can be stretched while drying, so that the clothes can be dried and improved. Drying effect.

In the embodiment shown in FIG. 12, the hot air blowing hole 59 having the side surface side blowing forming portion 57 shown in FIG. 6 is displayed. Therefore, the processing of steps S202 to S206 is performed, but the processing of steps S202 to S206 is performed. In the case where the hot air AW3 is blown only from the surface of the rotary wing 11, the The processing of step S202 to step S206.

As described above, in the present invention, the drying air, preferably hot air, is blown to the clothes existing at the bottom of the washing tank to dry the clothes, and is ejected from the bottom or side of the washing tank, or both. The stirring air, preferably hot air, blows the dried clothes, and the drying air is blown to the blown clothes for drying. In this way, the clothes can be blown up by the stirring air, and the drying air can be blown to the blown clothes, and the "wrinkles" can be stretched while drying, so that the clothes can be dried and improved.
